vENTILA'roR DEVICE.

To all whom t may concern: Y

-Be it knownl that I, ISAAC S. KEELER, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements vin Ventilator Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit ap-` pertains to make and use the same.

This invention relates to a ventilatorconstruction adapted to be used to holdpa door partiallyopen. This'construction may be used in several relations but is especially adaptedto be used in motor vehicles to hold the 'doors usually closing the front and rear compartments of the vehicle open a short distance, thereby permitting a circulation of air through the compartment.

AIt is the object and purpose of the invention to provide a device of this character which shall contain several new and useful features of construction Vand operation whereby a door may be rigidly held in par-V tially open position and insurance had against noise and rattling ordinarily occurring from the continual vibration to which a vehicle of this kind issubjected.

The construction by which these ends are attained is shown in the accompanying drawings, in which;

Figure 1 is an elevation, with the door shown in section, illustrating the ventilator device. Fig. 2 is a plan view of the construction shown in Fig. 1. Figs. 3 and 4 are sectional views taken on the line of Fig. 5 showing, respectively, the positions of the spring in the socket member when inoperative and when in use. Fig. 5 is a front elevation of the socket member .attached to the door; and Fig. 6 is a section on the line 6-6 of Fig. 1.

Like reference characters refer to like parts throughout the several views of the drawings. Y

In the embodiment shown the back of a seat is indicated at 1 and the door at 2. it being understood that the door is hingedly mounted so that its front edge may move back and forth with relation to the back 1.v

connected to the back 1 and carries a member 4 pivotally mounted'thereon. The con struction by. which this pivotal mount is made comprises a screw having an enlarged Specification of Letters Patent.

head 5, the shank 6 being threaded intokthe base 3 with the head positioned a distance above the base or substantially in the same plane with the outer surface of the member 4. VMember 4 is bored forming a cup adaptf ed to receive the head 5 and a strong coil s f spring -7 is interposed between the head and f i the lower or base portion of the cup. AIt will be evident that with the spring 7 kunder com-y pression member 4l continuously pressed against base3, and the spring insuresagalnst any rattling or lost motion of any character i taking Yplace between parts 3 and 4Q y* n Member 4 extends outwardly. a distance from the base '3 and atl its vfree end is provided with spacedfapart ears 8 between which arm 9 `is ypivotally mountedon the pin 10 which yis positioned `substantially vat right angles to the axis of the screw 6. Atits outer end arm 9 is enlarged forming a head l1. f i i vOn the inner member l2 is positioned andrigidly secured by means of the screws 13. The socket member is formed with a raised portion 14 yslotted verticallyas indicated at 15and having a substantially circular opening 16 at the upper end of the slot. large enough to receivek the head 11 while the slot is of sufficient widthto receive the arm 9 but will not permit the passage of thehead. A leaf face ofthe door 2 a socket into the socket member pressing against the end ofspring 17 as indicated in Fig. 4. By reason of the pivotal connection of member 4 to the base 3 on a horizontal axis and ofL the arm 9 on an axis 4at right angles to the axis of screw 6 a substantially universal joint isprovided permitting the location of i thev heady10 in a great number of positions Y and its engagementwith and disengagement from the socket'member is readilv accomplished. When engagedr in the socket member the pressure of spring 17 to the head 11 forces the head into contact with the inner side of the raised portion 14 guarding against rattling that would otherwise occur in the operation of the motor vehicle,anolV insuresa'gainst rattling, at thesame time permitting the Aready movement of the member e' with respect to the base 3 While the engagement of springl? With the head of -arin9 insures against rattling and other undue 4noise when the device is in operation.

y f-Springs 7 and A17 in effect absorb the vibration'oocurring from operation of the motor -vehicle and render the device practically noiseless when in use. Devices of this char- ,.acter areapplicable to doors` ofv any" type Whether hinged to swing from a forward pivot-or oneV at the rear 1n a` motor vehicle.

And furthermere,V all'r of these advantages 'resulting' from my construction are attained v bv a yvery ,Simple mechanism easilv manufactured and assembled at av comparatively low cost. I

` I claimzl. In a device of the character described,

a base adapted to be connected to a suitable support, a member provided with a cup at one end, a pivot member having an enlarged head passing through the cup and secured to the base, a spring located between the head and bottom of the cup and an arm pivotally connected to the member by a pin, the axis of which is disposed at an angle to the axis of the said pivot member. v. In combination, a support, a base secured thereto, a member pivotally connected to the base to turn about an axis normal-t0 the base, an arm having an enlarged head at its free end pivotally connected to the member to turn about an axis positioned substantially at right angles to the pivot-al axis of the member, a door, a socket member secured to the door having an upper opening adaptedv to permit the passage of the head on said arm, anda leaf spring secured at one end between an end of the socket member and the door, the other end thereof'extending forwardly to bear against said head, substantially as described.

Injtestiinonv whereof I affix my signature in presence yof two Witnesses.
